Abstract: An acoustic device includes an audio recording playback unit, an analysis unit, and an acoustic effect imparting unit. The audio recording playback unit records and plays back string independent acoustic signals for each string independent acoustic signal. The string independent acoustic signals respectively correspond to different strings of a stringed instrument and being independent from each other. The analysis unit analyzes at least one string independent acoustic signal from among the recorded string independent acoustic signals. The acoustic effect imparting unit imparts an acoustic effect to the at least one string independent acoustic signal for each string independent acoustic signal, based on a result of the analysis by the analysis unit.

Abstract: A sound generation device includes: at least one memory storing instructions; and at least one processor that executes the instructions to: output an output sound signal representing a performance based on performance data including a plurality of tracks each including at least one sound signal including an attribute; designate attribute information of the attribute of at least one of the at least one sound signal of at least one of the plurality of tracks as a search target; and search for a sound signal including the designated attribute information from the performance data. The performance in the output sound signal includes, omits, or changes the searched sound signal.

Abstract: A sound production control apparatus has a position detector that detects, in accordance with a playing operation of a musical instrument, a position of a key displaceable within a movement range from a start position to an end position. The movement range includes a sounding range including a sounding position and a setting range that is closer to the start position than the sounding range. The apparatus causes a played sound associated with the key to be produced upon the detected position of the key reaching the sounding position, while controlling a characteristic of the played sound depending on a displacement characteristic of the key within the setting range before the key is positioned in the sounding range.
